About Cubic Centimeter to Teaspoon Conversion

Converting cubic centimeter to teaspoon comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using teaspoon, or a laboratory protocol may specify volumes in cubic centimeter that need to be measured with equipment calibrated in teaspoon.

In everyday use, knowing that 5 cm³ = 1.014 tsp and 10 cm³ = 2.029 tsp covers most common situations. For bulk calculations, 100 cm³ = 20.29 tsp is a useful anchor. The reverse conversion — teaspoon back to cubic centimeter — uses the factor 4.929, so 1 tsp = 4.929 cm³.

All conversions use the internationally recognized factor of exactly 1 cm³ = 0.2029 tsp. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.

Quick Answer

Formula: Teaspoon = Cubic Centimeter × 0.2028842

Multiply any cubic centimeter value by 0.2028842 to get teaspoon. One cubic centimeter equals 0.2028842 tsp.

Reverse: Cubic Centimeter = Teaspoon × 4.92892

Worked Examples

One teaspoon
4.929 cm³ × 0.2028842 = 1.0000162 tsp
4.929 cm³ = 1 teaspoon.
One tablespoon
14.79 cm³ × 0.2028842 = 3.0006573 tsp
14.79 cm³ = 3 teaspoons = 1 tablespoon.
One US cup
236.6 cm³ × 0.2028842 = 48.002402 tsp
236.6 cm³ = 48 teaspoons = 1 cup.
5 mL dose
5 cm³ × 0.2028842 = 1.014421 tsp
5 cm³ = 1.014 teaspoons ≈ 1 medical teaspoon.

Frequently Asked Questions

About Cubic Centimeter and Teaspoon

Cubic Centimeter (cm³)

The cubic centimeter (also cc or mL) is the volume of a cube measuring 1 cm on each side. It has been part of the CGS system since the 19th century, formalized by the British Association for the Advancement of Science in 1874.

In medicine and pharmacy, the cc is the preferred volume notation for injection doses, IV drips, and surgical implants. Automotive engineers use cc to express engine displacement.

Interesting fact: Because 1 mL = 1 cm³ exactly, the units are fully interchangeable — medical staff say 'cc' while chemists say 'mL'.

Teaspoon (tsp)

The US teaspoon is exactly one-third of a tablespoon, 4.92892 mL. It was standardized in the US in the early 20th century partly to address inconsistent home medication dosing.

Teaspoons are the smallest standard cooking measure in the US system, used for spices, leaveners, and flavorings. A medical teaspoon dose conventionally means 5 mL.

Interesting fact: The teaspoon is behind one of science's most cited comparisons: the entire Pacific Ocean would fill roughly 7.1 × 10²³ teaspoons.
